Description

  The present invention relates to a restoration method for a damaged embankment that uses a large soil pad and a bar-shaped reinforcing material, and more particularly to a method for quickly restoring a bank that has been damaged (collapsed) by rainfall, an earthquake, or the like.

Conventionally, there have been the following problems related to restoration of embankments that have been damaged (collapsed) by rainfall, earthquakes, and the like.
(1) Construction method In the restoration of the embankment, the work of compacting the carried embankment material every 30 cm was necessary, which had a great influence on the restoration time.
(2) Loading and construction of embankment materials In many disaster areas, it was not possible to secure sufficient construction space, so it took time to construct embankments.
(3) Temporary restoration for early restoration When a railway or main road is damaged by rainfall or an earthquake, early restoration is often given priority over anything else. Therefore, in many cases, restoration as a temporary structure is often performed as “temporary restoration” giving priority to passing trains and cars. At this stage of temporary restoration, the strength and durability of the structure is lower than that of a normal structure (main structure), and therefore, a speed limit (slow speed) or the like is imposed on the passing vehicle.

Furthermore, in order to make the temporary structure a permanent structure, additional work is required.
None

  As described above, there were various problems related to restoration of embankments that were damaged (collapsed) by rainfall, earthquakes, and the like.

  In view of the above situation, the present invention has sufficient strength as a permanent structure for construction in a short period of time by using a large sandbag and a rod-shaped reinforcing material in combination, The object is to provide a rapid restoration method for damaged embankments that uses both large sandbags and bar-shaped reinforcing materials that can improve workability related to compaction and reduce the time required for restoration.

In order to achieve the above object, the present invention provides
[1] In the rapid restoration method for damaged embankments using both large sandbags and rod-shaped reinforcing materials, the collapsed surface of the damaged embankments is shaped, and large sandbags are installed on the shaped collapsed surfaces. It is characterized in that a bar-shaped reinforcing material is skewered in a stabbed manner.

  [2] In the rapid restoration method for a damaged embankment using the large earth crest and the rod-shaped reinforcing material as described in [1] above, the above-mentioned large earth crest surface construction is performed.

  [3] In the rapid restoration method for a damaged embankment using the large earth sand and the bar-shaped reinforcing material according to [1] or [2] above, the bar-shaped reinforcing material is placed in a horizontal direction with respect to the large sandbag. And

  [4] In the rapid restoration method of a damaged embankment using the large earth sand and the bar-shaped reinforcing material as described in [1] or [2] above, the bar-shaped reinforcing material is disposed above the large sand slag surface with respect to the large earth sand. It is characterized in that it is placed at an angle from the bottom downward.

  [5] In the rapid restoration method of a damaged embankment using the large earth sand and the bar-shaped reinforcing material as described in [1] or [2] above, the bar-shaped reinforcing material is placed in a horizontal direction with respect to the large earth sand and vertically It is also characterized in that it is placed like a skewer.

  [6] In the rapid restoration method for a damaged embankment using the large earth sand and the bar-shaped reinforcing material according to any one of [1] to [5] above, a geotextile is disposed between the large earth sand.

  In the present invention, a large sandbag is used as the soil as the embankment material. Therefore, transportation and construction can be performed easily.

  In addition, by reinforcing the stacked large sandbags with a rod-shaped reinforcing material, it is possible to obtain the proof stress necessary as a permanent structure at the stage of temporary restoration. Furthermore, the performance as a permanent structure can be satisfied by constructing a slope work at the time of this restoration. Since the construction of the slope work at the time of this restoration has little influence on the train running, the construction can be done while passing the train.

  The rapid restoration method of the damaged embankment using the large sandbag and the rod-shaped reinforcing material of the present invention is to shape the collapsed surface of the damaged embankment and install the large sandbag on the shaped collapsed surface. A bar-shaped reinforcing material is placed in a stab-like manner.

  Hereinafter, embodiments of the present invention will be described in detail.

  FIG. 1 is a diagram showing a rapid restoration method for a damaged embankment using a large earth sandbag and a bar-shaped reinforcing material in combination with an embodiment of the present invention. In addition, although the weight of a normal sandbag is about 40 kg, here, the weight of a normal large sandbag is 200 kg to 4 tons. Moreover, when it becomes long and long size, it may be several tens of tons.

  In FIG. 1, 1 is a supporting ground, 2 is an existing embankment, 3 is a damaged part in which a part of the existing embankment 2 has collapsed, and 4 is a track for train travel.

  Hereinafter, the construction method of the rapid restoration construction method of the damaged embankment which used the large earth sand of this invention and the rod-shaped reinforcement together is demonstrated.

  (1) First, as shown in FIG. 1A, the collapsing surface 5 of the affected part 3 of the existing embankment 2 is shaped.

  (2) Next, as shown in FIG. 1 (b), a long 1-ton sandbag is formed on the shaped collapse surface 5 as a large sandbag (for example, with a round lid with a diameter of 1100 mm and a height of 1080 mm). Install to stack.

  (3) Next, as shown in FIG. 1 (c), the rod-shaped reinforcing material 7 is skewered into a large sandbag 6. Here, although the rod-shaped reinforcing material 7 is constructed in the horizontal direction with respect to the large sandbag 6, the placement angle of the rod-shaped reinforcing material 7 with respect to the large sandbag 6 can be freely set. This is the temporary recovery stage.

  (4) Next, as shown in FIG.1 (d), the large sandbag 6 slope 8 is constructed. This is the main recovery.

  In this way, the large sandbags are stacked and the bar-shaped reinforcing material is skewered from the sloped surface. That is, by reinforcing the large sandbag 6 with the rod-shaped reinforcing material 7, it is possible to satisfy the proof stress necessary for the permanent structure.

  FIG. 2 is a diagram showing a rapid restoration method for a damaged embankment that uses a large sandbag and a rod-shaped reinforcing material according to a first modification of the embodiment of the present invention.

  In this first modification, the rod-shaped reinforcing member 7 ′ is placed with an angle from the upper side to the lower side of the large sandbag 6 with respect to the large sandbag 6.

  By configuring in this way, the bar-shaped reinforcing member 7 'is angled as compared to the case where the bar-shaped reinforcing member 7 is skewed in a horizontal direction with respect to the large sandbag 6, so The sandbag 6 can be stabilized.

  FIG. 3 is a diagram showing a rapid restoration method for a damaged embankment that uses a large soil pad and a rod-shaped reinforcing material according to a second modification of the embodiment of the present invention.

  In this second modification, the rod-shaped reinforcing material 7 is driven in the horizontal direction on the large sandbag 6 in a skewered manner, and the rod-shaped reinforcing material 9 is also driven on the large sandbag 6 in the vertical direction.

  By comprising in this way, when the embankment height is high and it is worried about protrusion, the rod-shaped reinforcing material 9 laid in the vertical direction works as a deterrent pile, and the large soil ridge 6 is greatly stabilized.

  FIG. 4 is a diagram showing a rapid restoration method for a damaged embankment using a large soil pad and a rod-shaped reinforcing material according to a third modification of the embodiment of the present invention.

  In the third modification, the geotextile 10 is laid between the large sandbags 6 that are stacked.

  Thus, when the stability at the time of construction cannot be ensured, laying the geotextile 10 between the large sandbags 6 makes the construction of the large sandbags 6 more robust and stable.
